1 barrel of crude oil = 42 US gallons (159 liters or 35 imperial gallons). It produces from about 35 percent to 42 percent of gasoline or petrol, plus many other products such… as kerosene, etc. More detail: The yield of gasoline from crude oil depends upon the quality of the crude oil ("Crude Type"), and the amount and type of processing at the refinery. So called "light" crude yields usually more gasoline per barrel than "heavy" crude, for a given amount of refinery processing. That a crude is "sweet" refers to sulphur content, - sweet makes it low sulphur and sour high sulphur, and a "package" to remove sulphur is called a "Crude Sweetener". Producing gasoline involves two steps in the refinery, beside post-processing. First is the distillation of the gasoline stream from the crude, and then the refomation of this to "hike it up". The final refomation is to adjust to the actual "Octane" numbers and add ingredients to make it suited for cars - such as lead in old days, now various alcohols and glycol to achieve the same. More extensive processing -- cracking, reformation, etc. -- can greatly improve yields, but of course, at the cost of the increased processing. Overall, refineries in the USA are yielding about 49% gasoline (20.5 gallons) from the mix of crudes they process (2004 data). Actually, a barrel of oil is 42 gallons. When the barrel is processed, you may get something like 15 gallons of gasoline, 9 gal. of fuel oil (See Gasoil / D2), 10 gal. of jet fuel (Kerosene) and 4 gal of other "heavy" products such as lubricants, grease, asphalt / bitumene and plastics and 4 gallons of lighter condensates/naphtha. In energy equivalents, 1 barrel=42 u.s. gallons of oil is estimated to be around 19.5 u.s. gallons of gas (natural gas). Not disputing the answer at all, but if crude is now $80 per barrel, this should make gasoline nearly $1,90 per gallon, and this without refining and transport costs and assumes that the other cuts of the crude can be sold to the same price! Depending on where you are the response varies. When oil is refined, there are number of products that will result from the refining process, including gas, diesel, and other products. Depending on the "feedstock" of the refinery and what production goals were in mind in constructing the refinery, the output of gasoline, diesel, and other products varies. For example, in the US, the refineries are aimed at maximum output of gasoline, so the crude types that are used produce about 2 liters of oil to process about 1 liter of gasoline. Change this, say use Canadian tar sand instead - and you will need 4 times the quantity of crude for the same amount of gasoline. In EU however, more crude types are used, and the gasoline cut differs, i.e. 1.5 to 3.0 liters. That a refinery process heavy crude will usually result in a good supply to the chemical industry of complex hydro-carbons that can be used to make e.g. Kevlar, resins for glue and fiberglass, and advance plastics. These plants will pay well for the chemicals, so operating a refinery is managing a complex equation. You may have a good agreement for producing the complex chemicals, there is a good market with a predicable price for gasoline, heating oil and jetfuel / kerosene - while the residue, huge amounts of bitumen or tar can only be sold at a low price as road and roof covering. In a barrel (42gal) of crude you need to divide it into separate parts. These parts are roughly: Naphta and other condensates that are liquid. 2gal Kerosene, where most is jet-fuel 4gal Unleaded gasoline 20gal Diesel fuel and heating/furnace oil 10gal Engine oil .5gal Gear oil .5galGrease .5galTar/asphalt 1gal So in a barrel of crude you can see that a small percentage actually becomes gasoline

Crude oil is feedstock for just about everything under the sun. When crude oil is refined, its various chemical parts are separated and some become gasoline, some lubricants, …some asphalt, and others the raw materials for plastics and rubber and many more things. Here are some examples of what can be obtained from petroleum (crude oil, natural gas, and/or viscous or solid forms): Fuels - like gasoline, diesel, propane (many people use propane to heat their homes), heating oil Heavy bottoms - like asphalt, bitumen, tar Petrochemicals - used as a feedstock for many everyday products: * plastic gadgets, tools, bags, toys * candles * clothing (polyester, nylon) * hand lotions * petroleum jelly * perfume * dishwashing liquids * ink * bubble gums * car tires * ammonia * heart valves * and many more ---- Crude oil is refined and used to make all these products: * Ethane and other short-chain alkanes which are used as fuel * Diesel * Fuel oils * Petrol * Jet fuel * Kerosene * Liquid petroleum gas (LPG) * Natural gas * Alkenes (olefins) which can be manufactured into plastics or other compounds * Lubricants (produces light machine oils, motor oils, and greases, adding viscosity stabilizers as required). * Wax, used in the packaging of frozen foods, among others. * Sulfur or Sulfuric acid. These are a useful industrial materials. Sulfuric acid is usually prepared as the acid precursor oleum, a byproduct of sulfur removal from fuels. * Bulk tar. * Asphalt * Petroleum coke, used in speciality carbon products or as solid fuel. * Paraffin wax * Aromatic petrochemicals to be used as precursors in other chemical production.

It varies alot. The minimum value is zero- as some crude oil are refined into other products. So, let's assume this is a crude that is economical to refine into gasoline. In t…his case , it can be as low as 2 gallons or as high as 23 gallons. (1 bbl = 42 gallons) Expressed as a percentage of the crude oil, this is 5 to 55%. (See attached links). The crude oil not refined as gasoline will be refined for other products. Common refined products from crude oil are provided in the related link, and will differ depending on the properties of the crude oil. It's very interesting that after refining, there will be more gallons of produced products than the original barrel of crude oil.
